[ArrogantBustard]

The Declaration of Independence is a philosophical document. It is a complaint, and apology (explanantion), and a justification for secession from an empire, and the formation of a new government. It offers almost nothing about the structure or function of that new government.

The Constitution of the United States is a practical document. It is a second effort at outlining and framing the specific form and function, powers, responsibilities, and limitations of the new government being established after the act of secession was made real.

DoI says nothing about specific form of government. It justifies the formation of one.

USC says nothing to justify the formation of the government. Such justification is assumed.

Good points. Although, I would assert that the founding paragraph of the republic, while being most certainly deeply philosophical and moral, is also eminently practical, in the same way that a cornerstone is practical. Take it away, and the entire edifice falls down, sooner or later.

"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among these are life, liberty and the pursuit of happiness. That to secure these rights, governments are instituted among men..."

Or, to use Frederick Douglass' nautical analogy, it is what keeps the pilot of the ship connected with the mast in the inevitable storms:

"I have said that the Declaration of Independence is the RINGBOLT to the chain of your nation's destiny; so, indeed, I regard it. The principles contained in that instrument are saving principles. Stand by those principles, be true to them on all occasions, in. all places, against all foes, and at whatever cost.

From the round top of your ship of state, dark and threatening clouds may be seen. Heavy billows, like mountains in the distance, disclose to the leeward huge forms of flinty rocks! That bolt drawn, that chain, broken, and all is lost. Cling to this day-cling to it, and to its principles, with the grasp of a storm-tossed mariner to a spar at midnight."

USC says nothing to justify the formation of the government. Such justification is assumed.

Largely true. However, the Constitution does have a statement of purpose, one which reflects the moral principles of our charter:

"We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution for the United States of America."

No offense, but Duh? That is obvious. You have not addressed my question. Why did they not carry the philosophy of the DoI into the USC?
